Stuck in RTC_EnterInitMode

[DS.4]

After connecting to a X-NUCLEO-LPM01A board for power consumption test , RTC init will not end.

Stuck in this while loop:

 

 tickstart = HAL_GetTick();
 /* Wait till RTC is in INIT state and if Time out is reached exit */
 while ((hrtc->Instance->ISR & RTC_ISR_INITF) == 0U)
 {
 if ((HAL_GetTick() - tickstart) > RTC_TIMEOUT_VALUE)
 {
 return HAL_TIMEOUT;
 }
 }

 

 Current solution: I have to program some example using stm32wbIDE, only that fixes it and I can now use my FW.

Hello @DS.4 ,

Make sure the RTC APB clock is enabled by checking the RTCAPBEN bit field , this could be due to some missing steps in the configuration of RTC and its clock source . This is just a guess if this does not resolve your issue i need further details on your configuration to help you solve this problem.

I will check that, 

Weird thing is even after aligning my init process to that of the example, it still won't work.

I still have to program the example and later my code.

I am running into this same issue on an example project for the STM32WLE wireless MCU. Has a solution been found? Can I provide any information to help solve the problem?
